What server am I thinking of?

Theres this server I used to play. It was in the roleplaying category I beleive. WHat you did was you could choose to be a mutant creature type thing and each had a special ability. I beleive it was like Squid water powers or something, lava powers or something, and night I beleive. You chose one and each had a special ability, like the squid could breath underwater and the lava mutant had immunity to lava and fire. I loved the server so could someone tell me what im thinking of? I think it has Towny aswell.
